Case study of H-series right angle gearbox for condensate water system driven by steam turbine

‌Project Background:
A certain power plant has ordered multiple vertical multi-stage drum bag type condensate pumps (small machine condensate pumps), matched with H-series right angle gearboxes, for the condensate water system driven by steam turbines.
Technical points:
·Pump type: Vertical multi-stage drum bag condensate pump (JLTDN series)
·Supporting: H-series right angle gearbox (90 ° steering)
·Power source: small steam turbine (horizontal output)
·Key requirement: Under high-temperature condensed water conditions, it is necessary to withstand the large axial force (≤ 125000N) generated by the self weight of the water pump
Analysis:
The condensate pump is a critical auxiliary equipment in power plants and requires continuous high reliability operation.
The core value of a right angle gearbox here lies in:
① Convert the power of the horizontal small steam turbine into a vertical shaft driven deep well pump;
② Directly bearing the huge axial thrust generated by multi-stage impellers, avoiding the need for additional thrust bearings on the pump body, and simplifying the pump body structure;
③ Easy to disassemble and assemble the drive end separately during maintenance.
